Abstract
A butt welding galvanized elbow is characterized by comprising a left elbow half right-angle arc (1) and a right elbow half right-angle arc (2), the left elbow half right-angle arc (1) and the right elbow half right-angle arc (2) are welded into the integrated galvanized elbow in a butting mode. The butt welding galvanized elbow has the advantages that inside and outside welding joint arc welding is performed for the two half right-angle arc work pieces in a punch forming mode in advance in the butting mode to complete welding, and the welding process changes the prior edge landing and withdrawing process.
Description
Technical field
The present invention relates to a kind of docking welding galvanized elbow, can be used for designing ventilation duct, gas transmission pipeline, environment protection ventilating system.
Background technique
At present, elbow bend adopts the scrap (bridge) wiredrawn edge to reach mostly.Such as ventilation duct angle coupling used.All the scrap (bridge) wiredrawn edge that adopts, so not only large to raw material (galvanized steel plain sheet) waste, and also jointing is done encapsulation process because the existence of wiredrawn edge is not easy the docking port place.And namely reduced raw-material loss with the elbow bend that novel process welds out, improved again the sealability of the mouth of pipe.
Summary of the invention
[0011] main purpose of the present invention is to provide the original scrap (bridge) wiredrawn edge of a kind of change compound mode, the docking welding galvanized elbow that the mode of employing docking port is welded.
Technological scheme of the present invention is:
A kind of docking welding galvanized elbow, by left elbow half right angle circular arc and right elbow half right angle circular arc, it is a whole galvanized elbow that described left elbow half right angle circular arc and the half right angle circular arc docking of right elbow are welded to connect.
Described left elbow half right angle circular arc and right elbow half right angle circular arc are symplex structure.
The outside butt welding knot of described left elbow half right angle circular arc and right elbow half right angle circular arc forms the outside weld seam, soldered in the inboard butt welding knot of left elbow half right angle circular arc and right elbow half right angle circular arc forms.
The invention has the beneficial effects as follows:
Docking welding galvanized elbow of the present invention
,Be characterized in the two halves right angles circular arc works with prior stamping, carry out inner and outer welding with the form of docking and carry out arc welding and complete.This welding procedure has changed original scrap (bridge) wiredrawn edge technique.
Description of drawings
Fig. 1 is one of structural representation of the present invention.
Fig. 2 is two of structural representation of the present invention.
In figure: 1 is that left elbow half right angle circular arc, 2 is that right elbow half right angle circular arc, 3 is that outside weld seam, 4 is interior soldered.
Embodiment
The invention will be further described below in conjunction with accompanying drawing:
As Fig. 1, a kind of docking welding galvanized elbow, by left elbow half right angle circular arc 1 and right elbow half right angle circular arc 2, it is a whole galvanized elbow that described left elbow half right angle circular arc 1 and half right angle circular arc 2 docking of right elbow are welded to connect.
Left elbow half right angle circular arc 1 and right elbow half right angle circular arc 2 are symplex structure.The outside butt welding knot of left elbow half right angle circular arc 1 and right elbow half right angle circular arc 2 forms outside weld seam 3, soldered 4 in the inboard butt welding knot of left elbow half right angle circular arc 1 and right elbow half right angle circular arc 2 forms.
The two halves right angles circular arc of docking of the present invention welding galvanized elbow is the weld seam of the three-dimensional of a solid.Become a right angle ventilation duct joint after welding.
Two of left and right workpiece is put into the frock folder wherein.Automatic argon arc welder shape inside and outside the elbow is welded successively.The workpiece boundary dimension that assembly welding is good, the sealability of weld seam has all reached usage requirement.
Embodiment recited above is described the preferred embodiment of the present invention; be not that the spirit and scope of the present invention are limited; do not breaking away under design concept prerequisite of the present invention; various modification and improvement that in related domain, common engineers and technicians make technological scheme of the present invention; all should fall into protection scope of the present invention, the technology contents that the present invention asks for protection all is documented in claims.
